IMPROVEMENT IN BELT-BUCKLES.

Specification forming part of Letters Patent No. 127,048, dated Muy 21,1872.

To all whom it may concern:

,Be it known that I, PHILIP M. Enns, of

' Youngstown, in the county of Mahoning and State of Ohio, have inventeda new and Improved Buckle for Machine-Belting; and I do hereby declarethe following to be a full, clear, and exact description of the same,reference being had to the accompanying drawing forming part of thisspecification, in which- Figure l is a perspective of the buckle appliedto a belt. Fig. 2 is a transverse section of the same, and Fig. 3 is alongitudinal section.

Similar letters of referenceindicate corresponding parts in the severalfigures of the drawing. My invention has for its object to provide forpublic use a strong, durable, and cheap fastening for machine-belting,which can be readily' applied and adjusted without danger of slipping ory casual displacement, To this end the invention consists in arectangular or quadrangular frame provided with a removable cross-barhaving several lateral projections or tongues upon each side which passthrough.

the ends of the belt, and bea-r equally upon the upper side of saidframe, as I will now proceed to describe, the tension of the beltholding the cross-bar and its tongues securely in the frame.

In the accompanying drawing, A is a rectangular frame, composed of metalor other suitable material. B is the metallic cross-bar extending fromend to end of the frame, where it is itted within notches or recesses C,which are formed by lugs d. rising from the upper surface of said frame.The ends of the crossbar B are placed within these recesses, beingattened to lit evenly therein, and are prevented frorn lateraldisplacement by the lugs d. The longitudinal movement of the bar isprevented by the lugs or shoulders e upon its under side, bearingagainst the inner faces of the end bars of the frame, as shown in Fig.3. The cross-bar is provided with two or more lateral projections ortongues F, upon each side which rest, at their ends, upon the sides ofthe. frame A. The number of tongues to be employed depends entirely uponthe size of the buckles, and this differs to correspond with belts ofdifferent widths.

The buckle is applied to a belt by passing the ends Gr of the latterbeneath the sides of the frame A, and extending the same upward betweensuch sides and the crossbar toreceive the tongues F, as shown in Fig. 1.After the tongues are passed through the ends of the belt, the cross-baris fitted in the recesses C, the weight and tension of the belt holdingit securely in place. The tongues and flattened ends ofthe crossbarshould bear equally upon the frame, so that the tension of the beltshall be evenly distributed among them. The side bars of the frame A areinclined outward or rounded upon their under vsurfaces to prevent thebelt from being cut or worn at these points in its passage round thepulleys, which would be the case if the bars were left with sharpcorners or angles.

To remove or adjust the belt it is only necessa-ry to slacken it orotherwise relieve the strain upon the cross-bar, when the latter can beeasily lifted from its place in the frame, and the tongues withdrawnfrom the belt or applied thereto in a different place, as will bereadily understood.

Having thus described my invention, what I claim is- The buckle formachine-belting, consisting of the frame A, constructed with the endrecesses O, and the crossbar having the tongues F, lugs c, and flattenedends, substantially as and for the purpose specified.
